i TELEPHONE ATTACHMENT.

Application filed February 12,1921. Serial No. 444,415.

To all whom it wm y concern Be it known that I, FAIRFIELD HoBAN, a citizen of the United States,- residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Telephone Attachments, of which the following: is a full, clear,

and exact specification.

This invention relates to attachments for telephones, and has for one of its objects to provide means for supporting the re ceiver, thus freeing the hand which is usually employed for holding the receiver to the ear.

Another object is to provide an attachment of this kind on which the receiver may be nicely adjusted to exactly register with the ear of the user when talking into the -mouth piece. A further object is to provide improved means for retaining the receivers'upporting arm in either of its positions, that is, when not in-use, as well as when in use. Further Objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views:

Figure l is a perspective view of a desk telephone showing my improved attachment applied thereto, the receiver-supporting arm being shown; in the position it occupies when the telephone is not in use.

Figure 2 is a fragmentary side view of the telephone and attachment showing the receiver-supporting arm in position for use in solid lines, and in the position it occupies when not in use in dotted lines, the corresponding positions of the receiver hook Ofthe telephone being also indicated.

Figure 3 is a detailed side View of the Outer end of the bracket of the attachment, showing the receiversupporting arm back in idle position.

Figure 4 is a detailed perspective view of part of the ball clamp at the free end of the receiver-supporting arm, and

Figure 5 is a detailed perspective View of the clamp forsecuring the bracket to the standard of the telephone.

In'Figures 1 and 2, an Ordinary desk telephone is shown with the usual standard 1, mouth piece 2, receiver 3, and receiversupporting hook 4. The receiver -is attached to a supporting arm 5 which is pivoted to an angularly bent arm 6 of a bracket 7 which is fastened around the standard 1 of the telephone just below the hook 4 by means of a clamp 8. As illustrated in Figure 5, said clamp 8 consists of supplemental semi-circular members 9 and 10, one of which may be integral with the bracket 7, while the other is preferably detachably secured thereto by a screw or bolt 11. The free ends of the members 9 and 10 of the clamp are interlocked at 12, preferably by the dove-tail or T-connection shown, which unites said outer ends of the members when their'inner end portions are connected by the screw 11, but which permits the separable member 10 to be entirely removed when said screw 11 is taken out in order to permit the ready application of the clamp about the standard of a telephone.

In order to permit the receiver to be ad justed so as to properly register with the ear of different users when they are speaking intothe mouth piece of the telephone, the arm 5 is provided with a telescopic extension 13 which may be set at different lengths by a clamping screw 14, and a ball 15 is formed at the extremity of said extension arm 13 to fit in a clamp 16 to which 1b: receiver is secured. Said ball clamp 16, as shown in Figures 1 and 4, comprises supplementaljaw members 17 and 18 having a concave portion at one end to engage the ball 15, while their other ends are spaced apart by an ,angularly bent portion 19 on one jaw interlocking with the other jaw by means of a tongue 20 on said part 19 fitting in a notch 21 in the jaw 18. looking connection between the jaws retains them in proper alignment when they are clamped together about the ball 15 by means of a set screw 22 which passes through the jaw 18 and engages a socket 23 in the shanks 24 of the receiver clamp 25, which shanks are secured to the inner face of the jaw 17 of the ball clamp by screws 26, Figure 4.

The receiver may be further adjusted by means of a set screw 27 on a projecting lug inter- 28 at the pivoted end of the arm 5, said set screw being adapted to engage a stop 29 extending into the bifurcated end portion 80 of the bent portion 6 of the bracket, so that by adjusting said set screw the forward swing of the receiver-supporting arm may be arrested at different points. The set screw 27 may be fixed in adjusted position by a locking screw 31. It will thus be seen that three dilierent means of adjusting the receiver are provided, namely, the telescopic extension arm 13, the universal ball joint 15, and the adjusting screw 27.

Pivoted on the bent portion 6 of the bracket 7, preferably by the same pivot bolt 32 which serves as pivot for the arm 5, is a lever 33 which extends along said bent portion 6 of the bracket and has its end passed through the loops 3% at the end of the receiver hook 4 of the telephone. At the other side of its pivot the lever 33 has a bent tongue 35 extending into the path of the lug 28 on the arm 5. The arrangement of said lever, tongue and lug is such that when the arm 5, which supports the receiver, is swung backward, as shown in Figure 1, and in dotted lines in Figure 2, the 111 28 engages the tongue 35 and moves the lever 33 and receiver book 4 downward to out off the circuit to the telephone, as is usually done when the receiver is placed on said hook.

To insure the proper retention of the receiver-supporting arm in its rearward or idle position for n'iaintaining the telephone circuit normally broken, a coiled spring 36 is fastened at one end to the bent portion 6 of the bracket at 87, and at the other end to a bent lug 38 on the pivot hub 39 of the arm 5, the arrangement of said lug 38 being such that it will be positioned at one side of the pivot 32 of said arm when the latter is swung backward to its idle position, as shown in Figures 1 and 3, and in dotted lines in Figure 2. lVhen the arm 5 is swung forward, as shoWn in solid lines in Figure 2, the lug 38 is brought to a position at the other side of the pivot 82, so that the spring :36 then serves to hold the arm in position phone circuit, even though said arm is not pushed all the way back manually. Obviously, the arrangement of the spring 36 will also insure the movement of the receiver-supporting arm to the limit of its forward movement for bringing the receiver into proper register with the ear of the user, and will hold said arm in that position while the instrument is being used.

I claim:

1. In av telephone attachment, the combination with a bracket and means for holding it in forwardly extending, associated relation with a telephone instrument, of a receiver carrying arm pivoted on the front end of the bracket and swinging between a position upwardly and rearwardly of said bracket and a position forwardly and upwardly of said bracket, a lever fulcrumed on the front end of the bracket and extending rearwardly alongside the same in a position to engage the receiver hook of an instrument, and means carried by the lower end of the receiver carrying arm and operating on the front end of the lever for moving the lever.

2. In a telephone attachment, the combination with a bracket and means for holding it in associated relation with a telephone instrument, of a receiver carrying arm pivoted to the bracket, and a lever pivoted between its ends on the bracket and coaxially with the arm, one arm of the lever being in the path of the arm, the other arm of the lever engaging the telephone receiver hook of the instrument to operate the same when said lever is moved by the arm.

In testimony whereof I have signed my name to this specification.

FAIRFIELD HOBAN.
